Delilah New Ropes, Samson the 14th Judge of Israel, Judges 16:11-12

Samson and Delilah – new ropes.
Samson said to Delilah after she had nagged him for the second time if you tie me up with new ropes I will become weak.
He had lied and just went his way.
Why did Samson not understand what Delilah was up to?
Or was God using this to get what was to happen in the Philistine temple Dagon where Sanson was to kill more in this one event than he killed while he was alive?
Philistines were one of the enemies of Israel.

Samson and Delilah

11 He told her, “If I’m tied up securely with new ropes that have never been used, then I’ll become weak and just like any other human being.”

12 So Delilah grabbed some new ropes and tied him up. Then she told him, “The Philistines are attacking you, Samson!” because some kidnappers were hiding inside an inner room. But he snapped the ropes from his arms like thread.Judges 16:11-12Delilah the full story- Judges 16:4-22.
